SPECIFICATION forming part of Letters Patent No. 649,252, dated May 8, 1900. Application led January 2, 1990. Serial No. 74. (No model.)

To all whom t may concern.:

Be it known that I, AMos F. MOREY, a citi- `zen of the United States, residing in Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Hydrocarbon-Gas Generators, of which the following is a speciication.

My invention relates to improvements in generators for evolving illuminating-gas from volatile hydrocarbons and aims to provide an efcient, convenient, and economical apparatus for supplying such gas for lighting residences, publie buildings, dac.v

In the drawings, Figure lis an elevation, mainly in central vertical longitudinal section, of the entire device. Fig. 2 is an eleva- .tion of one of the cores or plugs forming part of the generators herein described detached.y

Fig. 3 is a similar View o f the same plug on the side opposite to that shown in Fig. 2. Fig. 4. is ,a horizontal section through one of the generators-for example, on the line IV IV of Fig. l. Fig. 5 is a horizontal section on the line V V of Fig. I. Fig. 6 is a horizontal section on the line VI .VI of Fig. l.

. and leading to the burners 6 6a, which may y be of any preferred type, for supplying heat -valves S Si finner cores or plugs 10 l0, preferably of conto the generators 9 9. Said burners are mounted immediately below the generators,

.so that the flame and heat therefrom pass upward through central passages of the generators.

7 7 a designate supply-pi pes leading from the tank to the generators 9 9, of which I em- A ploy two; but it is obvious that the number might be increased or that the apparatus might be arranged to employ only one. Said pipes 7 7a arealso provided with suitable Said generators 9 9 consist of ical form, with corresponding central bores passing through them, and outer sleeves 1l Il, itting closely to the outer surfaces of said inner plugs and of equal length therewith. In the outer surfaces of said plugs are formed continuous grooves 12, preferably semicircular in cross-section and extending circuitously entirely around said surfaces in alternate circumferential and longitudinal lines, the object being tomake said grooves as long as possible in order to fully expose the liquid to be passed through them to the heat from the burners.

passages are formed, with the inner surfaces of said sleeves forming the outer wall of said passages.

The pipes 7 7a, leading to the generators 'from the tank, enter inlet-openings I3 13a in the lower ends of the sleeves 1l Il, whichopenings connect with the lower ends of the circuitous grooves or passages 12, as shown in Fig.L 5. At the upper ends of said passages are similarly connected at the opposite sides of the generators the ends of a pipe 14, as shown in Fig. 6, which pipe passes across from one generator to the other and is provided at its middle portion with a needlevalve l5, controlling an upwardly-'projecting nozzle 16.

The operation of the parts as thus far described has been substantially indicated. A sufficient air pressure having been established in the tank, the liquid is admitted to the burners 6 6a and ignited. As said burners project upward -into the central passages through the generators the heat rapidly raises the generators to a high temperature and the liquid being admitted thereto through the pipes 7 7 passes into the passages 12, where it is converted into gas, which passes into the pipe la and may be ejected through the valve l5 and nozzle 16. A cylindrical mixing-chamber 17, formed of sheet metal When said plugs l0 10n are tted within the sleeves l1 Il, closed' and open at the top, is mounted immediately above the nozzle 16 and rests upon the bosses 18 18 of the sleeves ll 11a. The bottoni of said mixing-chamber contains a central perjects.

upward through the top of said chamber to the distribution system. Said pipe is open at the `bottom and is supported, preferably, on legs 21, resting on the floor of chamber 17 and which hold the lower end of said pipe 20 elevated above said floor. In the annular space between pipe 2O and the upper edges of the walls of chamber 17 is placed horizontally a diaphragm 22, of wire-gauze or perforated metal, the function of which is to prevent the entrance into the mixing-'chamber of any foreign matters-such as dust, litter, floating particles, dre-while at the same time permitting the free passage of air into said chamber. On

the upper ends of the generators are mount-V fine-pipes 23 23a are `provided with a series of draft-openings 25 at their lower ends to promote the combustion at that point of any uneonsu'med gas which `may pass upward from the burners through the central passages of the generators. Then the gas formed by vaporization in the generators 9 is allowed to pass through pipe 14 and valve 15 into chamber 17, it becolnes mixed in said chamber and the lower-end of pipe 20, with the oxygen of the air-drawn down through the perforated top 22, anda new compound gas is evolved of the Agreatest efficiency and value as an illuminant. Said gas passes up the pipe 2O and into the distribution system and to the burners, which should be of the Bunsen or Welsbach type. The yhot airissuing from the central passages `through the generators passes up `the pipes 2323a and into the drum 24, Awhence any re` mai-ning `gases may be carried of, passing through the perforations in collar 24 into any convenient iiue or other outlet. The *hea-t from pipes 23 is communicated to the gas-discharge pipe 20, serving to produce an `upward draft through said pipe, and so draw in airinto mixing-chamber 17, and also to dry the lgas produced in said chamber and pipe 20, prevent condensation, and cause the gas 'tocirculate to the burners.

It is obvious that instead of locating the `tank "below the `burners anddepending upon lair-'pressure in the tank to elevate the `liquid I `'may locate said tank at a higher level and obtain the requisite flow by hydrostatic pressure in the ordinary way.

`-I have shown in Fig. 1 a lever 26 and a lratehet27, fixed on `the Wheel 15, for convenience'in openingthe valve. Said wheel is also provided with an index (not shown) 4which moves -around a circular dial 28 to indicate the amount of gas passingthrough the valve `but I'do `not claim novelty for these features. *Bythe operation of said valve the supply may be regulated according to the number of burners in use in the distribution system, the dial and index showing at a glance the amount being consumed.

It is obvious that a plant constructed as herein described may be readily adapted to the purpose of furnishing gas for heating or cooking purposes in furnaces, stoves, and the like.

I preferably arrange my apparatus when used for illumination purposes so that the gas produced will consist of about five parts of the hydrocarbon gas to ninety-five parts of oxygen.

I claim as my invention and desire to secure by Letters Patent- 1.
